RHD2 — Solanum tuberosum

Summary

PGSC0003DMG400014168 (RHD2, also known as RBOHC) on potato chromosome 3 encodes a respiratory burst oxidase homolog protein C, a NADPH oxidase with NAD(P)H oxidase H2O2-forming activity and calcium ion binding. This gene is associated with immune response-regulating signaling pathways, defense response by callose deposition, respiratory burst involved in defense response, and H2O2 biosynthetic process. It has been linked to root hair elongation, root hair development and tip growth, lateral root induction, root growth, and root epidermal cell differentiation. Associations also include grain yield, seed yield, biomass yield, bacterial blight disease resistance, late blight resistance, leaf rolling response, water use efficiency, stomatal resistance, transpiration rate, osmotic response sensitivity, cold tolerance, cadmium tolerance, phosphorus uptake, and aphid response. Studies of related genes in other species link the family to salt, heat, cold, and oxidative stress tolerance, as well as lateral root formation and photosynthetic induction.
